Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 200mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30
The AirTAC ACQJ32X200-30 is a double-acting, single-rod JIS compact cylinder featuring an external threaded stop with a lock nut that restricts the extend end position. You can fine-tune the extend stroke on the machine from 170 mm up to the full 200 mm without swapping components, while the retract stroke remains completely unaffected. This long-stroke variant is a made-to-order unit, as the 200 mm travel exceeds the standard 100 mm maximum for a 32 mm bore.
Because the piston area is unchanged, the output force is identical to a standard ACQ of this size, yielding 402.1 N push and 301.6 N pull at 0.5 MPa. The body uses a PT1/8 port, a 16 mm rod, and fixed NBR elastomer bumpers at each end for end-of-travel deceleration rather than adjustable pneumatic cushions. Sensor grooves are integrated into the body, though this specific configuration ships without a magnet.

| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| Rod thread | M8×1.25 (F) / M14×1.5 (B) |
Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30 Is Used
Multi-Part Machining Fixtures
Dial in the extend stop from 170 to 200 mm on a CNC lathe loader to accommodate raw stock of varying lengths without machining custom spacers.
Carton Changeover Stops
Rapidly adjust the end position on a packaging line's flap folder when transitioning between different box heights, securing the lock nut in seconds.
Prototype Press Testing
Find the exact 32 mm bore contact depth for a new assembly press by threading the external stop inward during R&D trials before finalizing the setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30 the Right Cylinder?
When sizing this unit, stepping down to a 25 mm bore drops the 0.5 MPa push force to 245.4 N, whereas stepping up to a 40 mm bore increases it to 628.3 N. If your application always operates at a fixed 200 mm extend position without variation, a standard non-adjustable ACQ cylinder will suffice. To order correctly, confirm the 32 mm bore, the 200 mm full stroke, the 30 mm adjustable window, the female M8x1.25 rod-end thread, and the M12x1.25 external adjuster thread. Remember that a plain compact cylinder will drift and cannot hold a load on air loss, so utilize an external rod lock or pilot-operated check valve if fail-safe holding is required.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X200-30 FAQ
This 32 mm bore cylinder provides 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 200 mm, but the external adjuster allows you to shorten the extend travel by up to 30 mm, giving a usable extend range of 170-200 mm.
The external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the stroke length only. It does not alter the piston area, so the force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at each end, not an adjustable air cushion, and this model ships without a magnet in the piston.
